DETAILED DESCRIPTION

In accordance with the present principles, a tiltable lid assembly 2 is provided. The tiltable lid assembly 2 is configured to be secured to a cup 6 or container that holds a substance, such as a liquid beverage or food product. The cup 6 or container may comprise a body having a bottom wall, side walls and an open top.

As shown in FIG. 1, the tiltable lid assembly 2 includes a base 10 and a cap assembly 4. The tiltable lid assembly 2 is configured to be attached to the body of the cup 6 over the opening. The base 10 of the tiltable lid assembly may have a collar portion 3 configured to be secured to the cup 6. In one embodiment, the collar portion 3 is secured to the cup by a press fit. In this embodiment, it is preferable that the tiltable lid assembly 2 includes a gasket 8 to provide an interference fit between the tiltable lid assembly and the cup 6. The gasket 8 also helps provide an air tight seal between the tiltable lid 2 and the cup 6. In alternative embodiments, the collar portion 3 includes threads 11 which permit the collar portion to be screwed onto the cup 6. In this embodiment, the gasket 8 may be positioned on a thread 11 and the gasket seals against the rim or the inside wall of the cup.

The base 10 has raised sidewalls 16 extending around its circumference. In one embodiment, the sidewalls 16 may have an increased height at the first end 14 of the base. As shown in FIG. 2, the base includes an opening 12 on the first end which serves a spout for the substance held in the cup. The substance may travel from the cup, through the opening and up the sidewalls 16 to reach the user's mouth. The sidewalls 16 are dimensioned to provide a controlled flow of the liquid substance to the user's mouth. The base 10 also includes an air vent 18 that is configured to allow gas to flow from the cup through the air vent in order to permit the substance to flow smoothly from the cup through the opening 12.

The cap assembly 4 is configured to be secured to the base 10 in order to cover the base and releasably seal the substance inside of the cup. As shown in FIGS. 1-2, the cap assembly 4 preferably has a relatively planar top surface 20. The cap assembly 4 includes a first end 7 and a second end 9 that is configured to be aligned with and overlie corresponding first and second ends 14, 17 of the base. The top surface 20 of the cap assembly may be dimensioned to have an area that substantially covers the portion of the base 10 that is surrounded by the sidewalls 16.

As shown in FIG. 6, the bottom portion 5 of the cap assembly may include a first seal 22 and a second seal 24. The seals 22, 24 may be overmolded or otherwise secured to the bottom portion 5 of the cap assembly. The first seal 22 is positioned on the first end 7 of the cap assembly and has dimensions that are configured to sealingly cover the opening 12 of the base. For example, the first seal 22 may be dimensioned so that a distal portion of the first seal may be received within the opening 12 of the base and completely cover the opening to prevent substances in the cup from flowing out of the opening. In one embodiment, the first seal 22 may be dimensioned to have a width that gradually increases from the distal end 23 to the bottom surface of the cap assembly.

The second seal 24 on the cap assembly 4 is configured to sealingly cover the air vent 18 on the base 10. The second seal 24 may be configured so that the distal portion 1 of the second seal may be received within the air vent 18 and completely cover the air vent to prevent gas from flowing through the air vent. The second seal 24 may be dimensioned with an increasing width from the distal end 25 to the bottom surface of the cap assembly. In the embodiment shown in FIG. 6, the second seal 24 is in the form of a plug which is configured to be received within the air vent 18 to seal the air vent. While the embodiments shown in FIGS. 1-6 include an opening 12 and air vent 18 in the base that is configured to be sealed by the first and second seals 22, 24, in other embodiments the base 10 may have additional openings and the cap assembly 4 has corresponding seals to sealingly close such openings.

In one embodiment, the cap assembly 4 may be configured to be releasably secured to the base 10. For example, the bottom portion 5 of the cap assembly may have fastening means 26 which is configured to be releasably secured to fastening means on the base 10. In the embodiment shown in FIGS. 1, 2 and 6, the base 10 may include a pair of mounting brackets 28 having recesses which are configured to receive raised circular protrusions 30 on a pair of arms 32 on the bottom of the cap assembly. The fastening means 26 releasably fastens the cap assembly 4 to the base 10 while the point of securement serves as a fulcrum which allows the cap assembly to pivot and provide a tilting motion to the cap assembly 4 when secured to the base 10. While the embodiments in FIGS. 1, 2 and 6 show a pair of mounting brackets 28 and arms 32, other fastening means known in the art may be used to releasably secure the cap assembly 4 to the base 10. In alternative embodiments, the cap assembly 4 may be permanently secured to the base 10 by any other means known in the art.

The tiltable lid assembly 2 also includes releasable locking means 34 which is configured to secure the cap assembly 4 in a plurality of positions with respect to the axis which it tilts about. For example, in a preferred embodiment shown in FIG. 3, the releasable locking 34 means is configured to secure the cap assembly 4 in a position wherein the first and second seals 22, 24 seal the opening 12 and air vent 18 of the base 10. In this position, the lid is locked in a sealed condition which ensures that the opening and air vent are closed. As shown in FIG. 7, in this position, the top surface 20 of the cap assembly may preferably have a substantially planar top that is easily viewable by the user as being in a level, non-inclined orientation. This permits the user to readily determine that the tiltable lid assembly 2 is in a sealed position which prevents liquid or air from being released from the cup.

In another preferred embodiment shown in FIG. 5, the releasable locking means 34 is configured to secure the cap assembly 4 in a position where the first and second seals 22, 24 are displaced from the opening 12 and air vent 18 of the base 10, respectively, and liquid contents of the cup and air may flow out of the opening and air vent. As shown in FIG. 8, in this position, the substantially planar top surface 20 of the cap assembly is easily viewable by the user as being in an inclined orientation. The top surface of the cup assembly may be inclined in this position approximately 5-60 degrees towards the first end 14 of the cap assembly. This permits the user to view the top surface 20 of the cap assembly and easily determine whether the opening/spout 12 is in an open position where the substance may freely flow out of the cup.

In the embodiment shown in FIGS. 2-5, the releasable locking means 34 includes a latch 36 that is connected to the cap assembly 4. The latch 36 has a distal end portion 38. The latch 36 also includes biasing means 40 that is positioned adjacent the latch. The biasing means 40 may be a spring, a magnet or any other biasing means known in the art. The biasing means 40 is configured to force the distal end 38 of the latch to extend towards the first end 14 of the base. The releasable locking means 34 may include an enclosure 37 which encloses the components of the releasable locking means on the cap assembly 4 except for the distal end 38 of the latch. The enclosure 37 may have an aperture that is configured to permit the latch 36 to extend outside of the enclosure. The base 10 includes a locking member 42 that includes an aperture 44 that is configured to receive the distal end 38 of the latch. When the distal end 38 of the latch is received in the aperture 44, the biasing means 40 maintains the distal end of the latch within the aperture to prevent axial motion of the cap assembly 4.

In one embodiment, the tiltable lid assembly 2 also includes a tab 46 that is connected to the releasable locking means 34 which is configured to permit the user to apply pressure opposing the biasing force to release the releasable locking means and permit axial motion of the cap assembly 4. The tab 46 is preferably positioned on the top surface 20 of the cap assembly. As shown in FIG. 2, the tab 46 may be connected to the releasable locking means by a post 47.

As shown in FIG. 4, when the user slides the tab 46 towards the second end 9 of the cap assembly, the distal end 38 of the latch is displaced from the aperture 44 and the securement by the releasable locking means 34 is released. When the user releases the tab 46, the biasing means 40 forces the distal end 38 of the latch towards the first end 7 of the cap assembly.

As shown in FIG. 4, when the cap assembly 4 is secured in a position where the first and second seals 22, 24 seal the opening 12 and air vent 18, the sliding of the tab 46 in a direction toward the second end 9 of the cap assembly opposes the biasing means to release the locking means and also naturally exerts downward force on the second end 9 of the cap assembly to incline the first end 7 of the cap assembly and decline the second end.

As shown in FIG. 5, when the user releases the tab 7 while the cap assembly 4 is in an inclined orientation, the distal end 38 of the latch is forced against a resting surface 48 on the locking member which secures the cap in the inclined position. The resting surface 48 preferably has dimensions that are configured to be complementary to the shape of the distal end in order to reduce friction of the distal end against the resting surface. For example, in the embodiment shown in FIG. 5, the distal end 38 of the latch is slanted upwardly approximately 45 degrees and the resting surface 48 is slanted downwardly at a similar angle.

The releasable locking means 34 are configured so that the user may push down on the inclined portion of the top surface 20 of the cap assembly to oppose the biasing force and force the distal end 38 of the latch away from the resting surface 48 to release the releasable locking means. This permits the user to easily release the securement provided by the releasable locking means. Alternatively, the user may slide the tab 46 towards the second end 9 of the cap assembly to release the releasable locking means 34. The user can then tilt the lid to a level position with gentle downward pressure on the first end 7 of the cap assembly. When the user releases the tab 46, the distal end 38 of the latch is forced into the aperture 44 of the locking member 42 to secure the tiltable lid assembly 2 in a sealed position.

Referring to FIG. 9, a method 200 for releasably locking a tiltable lid assembly that seals a cup in an open or closed position is provided. As previously described, the tiltable lid assembly may include a base and a cap assembly. The method 200 includes locking the tiltable lid assembly in the open position starting from the closed position by performing the following steps. In block 205, the releasable locking means are released. As previously described, the releasable locking means may be released by sliding a tab that is connected to the releasable locking means towards the second end of the cap assembly to oppose the biasing force and release the distal end of the latch, from the aperture of the locking member.

In block 210, the second end of the cap assembly is depressed to incline an opposed first end of the cap assembly. As previously described, the sliding of the tab that is connected to the releasable locking means towards the second end of the cap assembly may be sufficient to naturally depress the second end of the cap assembly and incline the first end of the cap assembly.

In block 220 the releasable locking means are activated. For example, the tab may be released so that the biasing force forces the distal end forward into a locked open position.

The method also includes locking the tiltable lid assembly in the closed position starting from the open position by performing the following steps. In block 230, the releasable locking means are released. As previously described, the releasable locking means may be released by the user depressing the inclined first end of the cap assembly. Alternatively, the user may slide the tab towards the second end to release the releasable locking means. In block 240, the first end of the cap assembly is depressed so that the cap assembly is in a level, non-inclined orientation. In block 250, the releasable locking means is activated. For example, the user may release the tab so that the latch is forced into the aperture of the locking member by the biasing means to secure the tiltable lid assembly in a closed position.
